pstopdffilter/pstocupsraster failed with err number -31000

Trying to print from Windows using Parallels 4.0 under Mac OS X Snow Leopard and getting the infuriating and useless error message “pstopdffilter/pstocupsraster failed with err number -31000”?
I spent a fair while Googling for a solution to this before stumbling across the answer: turn your printer off and back on. That’s it. No reinstalling drivers, adding or removing printers or playing with settings – just a good old fashioned power cycle. It’s nice to know some things never change :)
